| Abstract | PSR B0943+10 is the best studied radio pulsar exhibiting intriguing driftingsubpulses and the only one to have been detected in the X-rays and is thus theprime target for studying the relationship between the radio and X-ray emission.We propose observations which will definitely allow us to determine whether theX-ray spectrum is thermal or non-thermal and thus distinguish between vacuum-gaplike- and other pulsar emission models. The drifting subpulses in PSR B0943+10exhibit two modes, one where the drifting is clear and the pulses are strong(B-mode) and one where they are not (Q-mode). Coordinating these XMM-Newtonobservations with simultaneous radio observations will allow us to select X-raysassociated with the two modes and thus determine whether their spectra differ. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
